How to solve the 9th one?
I always get confused with problems involving mixtures of two or more components anyone know a general way of solving these questions?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.take out what is total moles of cl assuming complete dissociation
of all cl contaning compound
find out what amout of agno3 should be used
and do stoic correctly
ok wait no it is stated for samples
so there are 3 samples
eaxh with mass 0.535
write reaction
and see how much agno3 will be needed
for that sample
then back calculate the amount of volume with realting the specefic gravity and the mass percent
and see which sample requires most
thts the ans as i think
Not each
It’s the total mass of sample
that is the total?
let me think on this then
Name me please put concept :)
Could you share your thought process here?
They're asking 'mimimum'
So moles of sample must be minimum
Which means molar mass is maximum
Hence the sample is entirely KCl
Idk what they mean by every possible case in the end
Ok so basically whenever I encounter problems involving mixtures of like two components I usually write down whatever reaction they give in the question and then either take the weights as a variable or the moles as a variable after I find out the moles of product formed from stoichiometric and if the moles of product are given try to form equations to solve for composition of the elements in the mixture
In this case you are just have to find out the minimum amount of AgNO3. Which means the maximum amount of chlorine that comes out of these salts would come from the lowest weight of the other Ion ie NH4+
Does that help?
Idk man this is really confusing me
I just can’t seem to get the logic behind it
how is that the max amount of chlorine comes from the lowest weight of the ion, like i don't understand why
if the total mass is the same, and we remove something that has the minimum mass(cation), what remains must be the max mass, right? (Cl-)
oh right mb
thanks
